Need for more celebrations

It is nice to give and recieve presents in the darkest coldest time of the year. But why should this only happen once? I can easily imagine having a special day in every season when people exchange gifts. It would be good both for relationships and for the economy. I think we need to embrace some special seasonal occasions (solstices and equinoxes?) which would bring more cheer and expectations to our lives, and I am not talking just about kids. It feels wrong to have major celebrations only once a year.
